Midland Industries 77210 Solder Joint Coupling 2in C X C Copper

Product Description

The MIDLAND INDUSTRIES 77210 is a wrot copper solder joint coupling with a rolled tube stop, designed to join two 2-inch copper sweat connections in residential and commercial plumbing and hydronic systems. The rolled tube stop ensures consistent insertion depth and proper solder joint formation, which reduces callbacks from incomplete fills. Rated to 400 psi and suited for temperatures from 32 to 200 degrees F, the 77210 handles standard domestic water, heating supply, and similar fluid-distribution applications. Wrot copper construction provides the grain structure and ductility that licensed plumbers rely on for reliable, long-lasting sweat joints.

This coupling is used wherever a straight-run extension or repair is required in 2-inch copper pipe systems. Typical applications include potable water distribution, hydronic heating mains, and general mechanical plumbing in both residential and light commercial settings. The C x C end configuration accepts standard Type K, L, or M copper tubing prepared with proper flux and solder. This fitting is installed by licensed plumbers and pipefitters working to IPC or local plumbing code requirements.

Key Features

• Rolled tube stop ensures consistent pipe seating depth for repeatable, void-free solder joints
• Wrot copper construction delivers high ductility and pressure integrity
• 400 psi pressure rating supports demanding plumbing and hydronic applications
• Temperature range of 32 to 200 degrees F covers standard water and heating service
• C x C sweat end configuration compatible with standard copper tubing prep and soft or hard solder

Compatibility

Designed as an OEM-style sweat replacement fitting for 2-inch copper pipe systems requiring a straight coupling with an integrated tube stop.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the water or hydronic line and drain all fluid from the pipe section before cutting. Clean pipe ends and fitting sockets with emery cloth or a fitting brush, apply flux per the solder manufacturer's instructions, and sweat the joint using lead-free solder in accordance with IPC and local code requirements. Do not apply heat to a pressurized or water-filled line.
